The Stealth/ Whiplash comparison confuses me. Spiderwire Stealth, produced by the same company that made Whiplash (Pure Fishing, which owns a number of various brands including both Spider and Berkley), is quite a bit different from Whiplash. The braiding process is different in that Teflon and other materials are fused to the gel-spun polyethylene as it's woven in Stealth. Whiplash had a tighter braid and is coated after the fact, I believe.

There are other differences, but the PR guy I talked to wasn't as sure as he was about the above.

Both are good lines, but they are different. I like Whiplash for bottomfishing, Stealth for backing on fly reels and in freshwater applications, FireLine in several applications where I think it excels. They're all tools, and should be used that way.
